<li> Added the [sqlite3_create_function_v2()] interface that includes a
     destructor callback.
<li> Added support for [custom r-tree queries] using application-supplied
     callback routines to define the boundary of the query region.
<li> The default page cache strives more diligently to avoid using memory
     beyond what is allocated to it by [SQLITE_CONFIG_PAGECACHE].  Or if
     using page cache is allocating from the heap, it strives to avoid
     going over the [sqlite3_soft_heap_limit64()], even if
     [SQLITE_ENABLE_MEMORY_MANAGEMENT] is not set.
<li> Added the [sqlite3_soft_heap_limit64()] interface as a replacement for
     [sqlite3_soft_heap_limit()].
<li> The [ANALYZE] command now gathers statistics on tables even if they 
     have no indices.
<li> Tweaks to the query planner to help it do a better job of finding the
     most efficient query plan for each query.
<li> Enhanced the internal text-to-numeric conversion routines so that they
     work with UTF8 or UTF16, thereby avoiding some UTF16-to-UTF8 text
     conversions.
<li> Fix a problem that was causing excess memory usage with large [WAL]
     transactions in win32 systems.
<li> The interface between the VDBE and B-Tree layer is enhanced such that
     the VDBE provides hints to the B-Tree layer letting the B-Tree layer
     know when it is safe to use hashing instead of B-Trees for transient
     tables.
<li> Miscellaneous documentation enhancements.

newsitem {2010-October-08}  {Version 3.7.3} {
  SQLite [version 3.7.3] is a regularly scheduled bi-monthly maintenance
  release of SQLite.  Upgrading from [version 3.7.2] is optional.
  Upgrading from all other releases is recommended.

  This release adds two new interfaces (really just variations on existing
  interfaces).  The [sqlite3_create_function_v2()] interface adds a 
  destructor for the application-data pointer.  The new 
  [sqlite3_soft_heap_limit64()] interface allows the soft heap limit to
  be set to a value greater than 2<sup>31</sup>. 

  The [RTREE] extension has been enhanced with the ability to have an
  [custom r-tree queries | application-defined query region].  This might
  be used, for example, to locate all objects within 
  the field of view of a camera.

  The 3.7.3 release also includes some performance enhancements, including
  query planner improvements, documentation updates,
  and fixes to some very obscure bugs.

newsitem {2010-August-24} {Version 3.7.2} {
  SQLite [version 3.7.2] fixes a long-standing bug that can cause the
  database [free-page list] to go corrupt if [incremental_vacuum] is used
  multiple times to
  partially reduce the size of a database file that contains many hundreds
  of unused database pages.  The original bug reports together with links
